Computer application power management

Procurement Notes

Verify the specific ordering suffix 'BK TIN/LEAD' to confirm the tin/lead plating option, as standard versions may differ. Confirm availability status directly with the manufacturer or authorized distributors, as discontinuation notices exist for adjacent part numbers in the series. Ensure compliance with project-specific material requirements regarding lead content before finalizing procurement orders.

Selection Notes

Select this component when a 4.7 V reference with 1 W power handling is required in a through-hole DO-41 package. Consider the specified 5% voltage tolerance and 8.0 Ω impedance limits for precision requirements. Evaluate the wide operating temperature range for environments subject to extreme thermal conditions. Verify that the tin/lead plating meets the assembly process specifications.
